There is enough money to feed and house every homeless person many times over

I went on a bike ride just recently.
Down a trail where alot of homeless camps are.
I saw a bunch of donated food that was just thrown to the side of the trail.
Full loaves of good bread that cost over five dollars a loaf gone completely to waste.
Sad but true.

you bet. Some are generous philanthropists, but some give nothing publicly anyway.

Ask about the foreign aid budget and compare it to support for citizens in need.
